Caffeine adsorption by using cyclodextrin hydrogel
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 12/7/2019)Caffeine is found in various kinds of food and drink and it can affect the human nervous system. This research aims to prepare the hydrogel between cellulose and β-cyclodextrin from co-precipitation and crosslink method. ... -
Development of Bio-based Epoxy Materials from Vegetable Oil
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 4/7/2023)Epoxy material from vegetable oil has more attention because of its environmental friendliness. In present research, a bio-based epoxy resin formulated from the crosslinking reaction between epoxidized linseed oil and ... -
Influence of linseed oil and its derivative on moisture absorption and mechanical properties of thermoplastic starch
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 12/7/2019)Thermoplastic starch (TPS) is a bio-based and biodegradable polymer that has tendency to replace many petroleum-based polymers. However, one of the important weakness of TPS is moisture sensitivity. This research aims to ... -
Morphology and mechanical properties ofbacterial cellulose/modified natural rubber blend
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 12/7/2019)The aim of this research is to improve the elasticity of bacterial cellulose with natural rubber and modified natural rubber. Dextrin-grafted epoxidized natural rubber (ENR-Dex) was obtained by grafting dextrin onto ENR. ... -
Study on preparation and absorption of hydrophilic-hydrophobic hydrogels
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 18/6/2021)The hydrogel is a three-dimensional structure material made from hydrophilic polymers. Hydrogel, therefore, can absorb and contain a lot of water. The primary aim of the present work is to develop the elastic porous ... -
study on preparation and water absorption of cellulose / oligo-chitosan hydrogel
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 18/6/2021)Water-absorbing materials can be synthesized from hydrophilic polymers. Cellulose and chitosan are the natural polymers, which have a potential to prepare water-absorbing materials. The conventional cellulose/oligo-chitosan ... -
A study on properties of Thermoplastic starch (TPS)/Polycaprolactone (PCL) blend compatibilized by vegetable oil
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 10/7/2020)The primary purpose of this research is to improve the mechanical properties of thermoplastic starch (TPS) by blending with polycaprolactone (PCL). TPS and PCL were chemically modified by grafting with maleic anhydride ... -
Synthesis and properties of resin from epoxidized oil and Poly(butylene succinate)
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 10/7/2020)Bio-based resins have been an interesting polymer since they can be derived from renewable resources. In this research, the bio-based resin was prepared by a reaction between epoxidized vegetable oil and an oligomer of ...
